SSD DC 6 System Requirements Hardware Requirements 1. SSD The following Samsung SSDs are supported: (* : Limited support Cannot update FW) - Samsung SSD 845DC PRO - Samsung SSD 845DC EVO - Samsung SSD 850 PRO - Samsung SSD 840 PRO - Samsung SSD PM853T * - Samsung SSD SM843T * - Samsung SSD SV843 * 2. Others On Marvell controller, the Magician feature may not work properly after hot plugging. Software Requirements Operating system OS RHEL 5.7 and later RHEL 6.1 and later CentOS Comments Refer to the C600 chipset table below Refer to the C600 chipset table below Follows the same limitations as RHEL above Ubuntu 12.04 LTS - Limited support for the Intel C600 chipset families due to the well-known ISCI (Intel SAS Driver) driver issue. (https://github.com/xilinx/linux-xlnx/commits/master/drivers/scsi/isci?page=1)
SSD DC 7 OS Feature support Comments RHEL 5.7 and later Limited support for some ATA commands including Secure Erase, Set Max Address, and FW Update RHEL 6.1 and 6.2 Limited support for some ATA commands including Secure Erase, Set Max Address, and FW Update RHEL 6.3 RHEL 6.4 and later Limited support for some ATA commands including Secure Erase, Set Max Address, and FW Update. But it can be fully supported when patched with ISCI 1.4 for RHEL 6.3 (refer to comments on the right) Full support http://sourceforge.net/ projects/intel-sas/files/ RHEL6.3%20Driver%20 Update%20v1.4.1/ * Limitation of support for C600 chipsets has been determined by evaluations and tests. On Marvell controller, Magician feature may not work properly after hot plugging. On Linux systems, the tool must run with root privilege. This can be done through either sudo or su commands. Known Issues TRIM command supports only ext4 file system. Set Max Address and Secure Erase require a power cycle of SSD. Set Max Address may not work on some Ubuntu distributions due to libata restrictions. Over-Provision only adjusts the last partition for a disk with multiple partitions. The following operations are supported for SSDs when connected through the LSI HBA cards: o List, Firmware Update, Secure Erase, SMART, Set Max, Write Cache, SCT Cache State, Disk Information, Command History, and Help. features.
